AGRICULTURAL IMPLEME'DIT.

Original application filedl'une 22, 1921, Serial No. 479,610. Dividedand this application filed February To aZZwhom it may concern 7 Be itknown that 1, WILLIAM D. DnwnNn, a citizen of the United States, and aresident of South Bend, in the county of St. Joseph and State ofIndiana, have invented certain new and useful Improvements inAgricultural Implements; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in agricultural implements andmore particularly to such as are known in the art as pulverizing, thisapplication being a division of application filed by me on the 22nd dayof June, 1921, and designated by Serial No. 479,610.

One object of my present invention is to so construct a pulverizerhaving a roller comprising disks mounted on a shaft, that the diskscomprising said roller may be readily assembled or dis-assembled.

lVith this and other objects in view, the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is a view in side elevation of apulverizer in which my improvements are embodied; Figure 2 is a view,partly in elevation and partly in section illustrating the structure ofone of the rollers and means for mounting the shaft thereof, and Figure3 is a view showing one of the sectional disks.

The main frame of the implement may comprise parallel beams 1, 1,suitably spaced apart and connected by depending brackets such as shownat 2. Draft beams such as indicated at 3 may be secured to the frame andcarry a draft attaching member 4c.

To each depending bracket 2, a secondary frame 5 is pivotally connected.

Bearing boxes 6, are suitably mounted near respective ends of eachsecondary frame for the accommodation of shafts 7 of rollers 6, 9,-cachof the latter comprising hollow disks 10 and 11,the disks of the frontroller 8 being larger in diameter than the disks of the rear roller 9.The disks of each roller are made hollow and provided with peripheralearth-engaging portions which are tapering or approxi- Serial No.536,147.

' ma-tely V-shaped in crosssection. The disks 10 of each roller areprovided with web portions 12 on which hubs 13 are formed, the latterbeing mounted on the shaft 7 of the roller, and side edges of the disks10 are provided with annular flanges 14:. The disks 11, which alternatewith the disks 10, are made each in two parts 11 11 and these parts areprovided at their side edges with laterally projecting flanges 15 which,when the disks are assembled, are embraced by the annular flanges 14 ofthe disks 10 and thus the two-part disks 11 are supported by and betweenthe disks 10. By constructing the disks as above explained, they can bereadily assembled or disassembled. The disks of each roller and thebearing boxes are held in place on the shafts 7 by means of nuts 16screwed on threaded shanks 17 at the ends of each of said shafts andengaging the bearing boxes 6, and the use of bolts for securing thedisks together is obviated. The threads of the shanks 17 are such as toprovide adjustment for variations in the width of the disks and lengthsof the bearing boxes, when the nuts 16 are turned. It will be observedthat by unscrewing the nut 16 at one end of one of the shafts 7, thedisks may be so moved on the shaft as to free the flanges of the disks10 from the flanges of the two-part disks 11, so that the latter may bereadily removed. The nuts 16 may be held in the positions to which theymay be adjusted, by means of jam nuts 17 The bearing boxes 6 arethreaded as shown at 18, and these portions are engaged by internallythreaded caps 19 which bear against the secondary frames 5. The caps notonly enclose the outer ends of the bearing boxes and threaded ends ofthe shafts and the nuts thereon, but they also afford means ofadjustment to provide for variations between the length of the shaft anddisk assemblies and the distance between the secondary frames. It willalso be seen that by turning the threaded caps 19, at the ends of one ofthe rollers, the assembly may be so adjusted that the disks thereof maybe made to bear proper alternate relation to the disks of the otherroller. To hold the parts in proper adjustment, the caps 19 may be secured to the bearing boxes 6 by means of set screws 20.

Having fully described my invention What I claim as new and desire tosecure by Letters-Patent is 1. A pulverizing roller comprising a shaftand tWo sets of disks, the disks of one set mounted on said shaft andalternating with the disks of the other set, the disks of thelast-mentioned set each comprising a plurality of parts havinginterlocking connection with the disks of the first-mentioned set. V

2. In an implement of the character described, the combination Withsupporting means, of a pulverizing roller comprising a shaft mounted insaid supporting means, a set of disks mounted on' said shaft, andmulti-part disks disposed between the firstmentioned disks and havinginterlocking relation thereto.
